The dental floss is a tool for cleaning interdental spaces. It is enough to use dental floss once a day before brushing your teeth.
You can acquire dental floss in the pharmacies or drugstores; you can find 25 or 50 meters in one package.
Execution: The proper length of a piece is abouth 40 cm, you can work comfortably with this (if you open the box, you can tear the length you require with the help of a metal ear).
Wind the floss on your two index fingers, so that only 5 cm are left free. Slide the floss between your teeth until the gingival papilla. If you have reached this place, tighten the floss onto the surface of the tooth and pull it upwards in the interdental space. You should apply these techniques for every interdental space, paying attention not to hurt the papilla.
Don’t let the initial difficulties discourage you, try again next day, and you will see, your technique will get better each day!
